Empirically we buy a company, tell the accounting team that we are changing to gsuite and see if the CTO gets fired, or the accounting team quits, or the company gets a hit.
I'd leave a moderately-sized (like 5 pages) work gdoc page open on my work machine at Google and come back the next day and it was using 1gb of RAM. Fantastic is certainly one word for it.
Collab tools are fabulous no doubt, but sheets feels entirely neglected and basic.
Permissions model is clunky and gsuite governance is nonexistent - you have to buy a CASB license to do anything effectively.
It's not a bad suite, I just think it's confused on some areas (don't even get me started on the chat/conference systems tho)
